So, What is Actually the Distance from the Equator to the Pole? - Overview of the Meridian Distance Approximations
1 Gdynia Maritime University, Gdynia, Poland
ABSTRACT: In the paper the author presents overview of the meridian distance approximations. He would like to find the answer for the question what is actually the distance from the equator to the pole - the polar distance. In spite of appearances this is not such a simple question. The problem of determining the polar distance is a great opportunity to demonstrate the multitude of possible solutions in common use. At the beginning of the paper the author discusses some approximations and a few exact expressions (infinite sums) to calculate perimeter and quadrant of an ellipse, he presents convenient measurement units of the distance on the surface of the Earth, existing methods for the solution of the great circle and great elliptic sailing, and in the end he analyses and compares geodetic formulas for the meridian arc length.
KEYWORDS: Great Circle (Orthodrome), Great Elliptic Sailing (GES), Geodetic Aspects, Meridian Distance, Meridian Distance Approximations, Distance from the Equator to the Pole, Polar Distance, Nautical Mile
